Late Mesozoic–Cenozoic evolution of the Sanjiang Basin in NE China and its tectonic implications for the West Pacific continental margin

Reconstruction of northeast Asian deformation integrated with western Pacific plate subduction since 200 Ma

“…the Late Cretaceous fore-arc basin, the Late Cretaceous Sanbagawa metamorphic belt, the Jurassic Chichibu accretionary complex with Cretaceous strike-slip basin sediments, and the Late Cretaceous Shimanto mélange in southwestern Japan, likely constitute a continuous subduction-related island arc system from southeast Korea to southwest Japan (Isozaki et al, 2010a;Zhang et al, 2012) (Fig. 1 and Table 1).…”

Late Holocene slip rate and average recurrence interval of great earthquakes on the Shangzhi segment of the Yilan‐Yitong Fault Zone, northeastern China: Constraints from paleo‐earthquakes and historical written records

“…In addition, an array of folds and reverse faults with minor right‐lateral strike‐slip movement of the same age in the middle to southern portions of the TLFZ are discovered in seismic profiles and trenches from the Anhui segment (Chen & Nábelek, ; Chen et al, ; Tang, Shen, Lin, & Zhang, ; Wang et al, ), the Jiangsu segment (Liu et al, ), the Shandong segment (Ju et al, ), the Bohai Bay Basin (Hsiao et al, ; Li et al, ; Wan, Tang, Zhou, Jin, & Chen, ; Xu et al, ; Zhao & Zheng, ; Zhu et al, ), and the Liaohe western depression (Li & Vander Hilst, ). The same features are present along the northern part of the YYFZ (Figure b), including the Shulan Basin (Min et al, ; Yan, Zhu, Lin, & Zhao, ), the Fangzhen Basin (Chen et al, ), and the Sanjiang Basin (Zhang et al, ). Furthermore, the focal mechanisms of strong earthquakes that have occurred along the TLFZ, GPS data, and in situ stress measurements all indicate that nearly east–west compression resulted in reverse right‐lateral strike‐slip motion on the faults in the late Quaternary (Hsiao et al, ; Liu et al, ; Zhang et al, 2003; Zhu et al, ).…”

“…Although there is a lack of written records of strong earthquakes due to the underdeveloped ethnic minorities, changes in the languages, natural hazards and ongoing wars between minority groups, the YYFZ has been speculated to have the greatest deformation and highest gradient of stress accumulation and thus to be the most likely location for potential catastrophic earthquakes because it is the main boundary fault between the active tectonic blocks of Xingan‐East Mongolia, Yanshan and Northeast China (Zhang et al, , ). Over the past several decades, its structural features (Liu et al, ; Shi et al, ; Su et al, ; Tian & Du, ; Tong, Yu, & Geng, ; Zhu et al, ), Mesozoic–Cenozoic evolution (Dong et al, ; Gilder et al, ; Hsiao et al, ; Huang et al, ; Xu & Zhu, ; Zhu, Niu, Xie, & Wang, ; Zhu, Zhang, Xie, Niu, & Wang, ), relationships between faults and basins (Allen, Macdonald, Xun, Vincent, & Brouet–Menzies, ; Chen et al, ; Chen & Nábelek, ; Tang, Yang, Guo, & Tang, ; Yu, Min, Wei, Zhao, & Ma, ; Yu et al, ; Zhang et al, ; Zhang, Min, Deng, & Mao, ; Zhang et al, ; Zhou et al, ), potential oil and gas resources (Wang, ; Yang & Xu, ) and regional geodynamic processes (Fletcher, Fitches, Rundle, & Evans, ; Huang & Zhao, ; Ren, ; Ren, Lu, Li, Yang, & Zhuang, ; Ren, Tamaki, Li, & Zhuang, ; Wu, Xu, Zhu, & Zhang, ; Yin, ; Yin & Nie, ; Zhang, Zheng, Zheng, Wang, & Zhang, ; Zhao, ; Zhu, Chen, Wu, & Liu, ; Zhu et al, ) have been studied intensively. However, many controversial issues about the late Quaternary deformation of the YYFZ remain, especially with respect to its slip rate and the average recurrence interval of major earthquakes in the late Quaternary.…”

Geochronology and geochemistry of Late Triassic bimodal igneous rocks at the eastern margin of the Songnen–Zhangguangcai Range Massif, Northeast China: petrogenesis and tectonic implications

“…The shaded areas are the other Late Triassic igneous rocks from the region (Wang et al 2015a). K-Ar ages are unreliable due to the occurrence of latestage tectono-magmatic events (such as Early Jurassic, Early Cretaceous, and Late Cretaceous magmatic events; Ji et al 2007;Yu et al 2012;Zhang et al 2012;Xu et al 2013) that affected the study area, which may result in Ar loss. New zircon ages, supported by field relationships including cross-cutting intrusions, indicate that the inferred Palaeozoic ages of these units should be reviewed (Meng et al 2011).…”
